org.apache.hadoop.mapred.lip.input.invalidInputException

i run this code in power shell by following the steps and commands for pwer shell in this tutorial.
i just change the name from WordCount to Matrix.
all the steps work fine, But i get this error after run the Azure PowerShell script:

exception in thread main org.apache.hadoop.mapred.lip.input.invalidInputException:input path does not exist

Based on my understanding, I think you want to calculate for matrix multiplication in Azure HDInsight. And you could ran your code in HDInsight Emulator successfully, but failed in HDInsigit on Azure.

The file path on HDFS of Azure HDInsight is directly use the relative path based on the blob container as root path without host information if you remote into the cluster, such as wasb:///examples/data/....

So you can try to remote into the HDInsight Cluster and run the code in the remote ssh for Linux or cmd for Windows, and follow the steps below.

Copy your mapreduce jar file and data file into HDInsight Cluster. For example of Hadoop on Linux, you can command scp <your-file> <ssh-username>@<hdcluster-name>-ssh.azurehdinsight.net:/home/<hdcluster-username>/.
